In general, you can fix this error by clicking preferences at the top right of the Graboid window and setting your complete folder path to c:\Graboid\Complete. Also, please make sure that you are using the most recent release of the software, which can be downloaded here.

There are several configuration issues that can cause this problem:

1. Click the status button on the In Progress line in the downloads tab. Sometimes that tells you the problem.

2. Graboid may simply have opened up too many simultaneous connections to the server where the content resides, and that server is denying access. You can usually solve the problem by shutting down Graboid for 15 minutes or so (the connections will reset).

3. Only one instance of Graboid can be used for downloading or streaming at a time. Make sure no-one else is using your account.

4. The download may be stuck. Try quiting Graboid, deleting the “Graboid Temp” folder from your download directory, and re-adding the video to your queue.

5. Right click the Graboid icon on your desktop, select run as…. and run as administrator, or remove the protection from unauthorized use.

6. Turn off your firewall. If that solves the problem, then give Graboid permission to go through and turn it on again.

This usually happens because the Graboid player has opened up too many simultaneous connections to the server where the content resides, and that server is denying access. You can usually solve the problem by shutting down Graboid for 15 minutes or so (the connections will reset).

This can be caused by the folder name being too long, when coupled with the long names of some video files. In general, you can fix it by clicking preferences at the top right of the Graboid window and setting your complete folder path to c:\Graboid\Complete.
